		// There are some useful functions/classes that you should know to make your own custom inspector!

		// EditorGUILayout holds a bunch of utilities to display various fields in the inspector
		// LabelField shows a string
		// FloatField shows a editable float
		// Toggle shows an editable bool
		// IntSlider shows an editable int...

		// To show these values we first need to get the individual property we want to show
		// Any variable that is either public or uses serializefield can be accessed through the function FindProperty

		// In OnInspectorGUI from a class using the CustomEditor attibute we have access to serializedObject
		// which holds the data of the object were looking at in the inspector!

		// SerializedObject -> Class or Monobehaviour as you might be used to
		// SerializedProperty -> Variable/Property/Field of that Class/Monobehaviour

		// serializedObject.FindProperty(string propertyName) gives us a serializedProperty which we can then use in the
		// EditorGUILayouts as described above

		// Now with our found property (which is of type: SerializedProperty), we can read/write our data through a few accessors:
		// serializedProperty.intValue
		// serializedProperty.boolValue
		// serializedProperty.floatValue...

		// Interestingly this serializeObject/Property thing lets us edit these fields without making them publicly accessible
		// That's the magic of serialization in Unity I guess
		// With this ability you can hide/show information only when you want it
		// Below, when in Twitch Mode I hide most of these variables because they simply don't matter in Twitch Mode
		// Similarly, when in Attract Mode I reveal a bunch of data that's only relevant to that mode

		// Last thing, to save all your changes, it's important to save your changes with
		// serializedObject.ApplyModifiedProperties();
		
		// I also do the BeginChangeCheck and EndChangeCheck because Unity's documentation says it's good to do (probably for performance?)
		// But all this will totally still work with or without it
